“I think we definitely will be able to win a race at some point during the season,” Hamilton was quoted as saying by Autosport following his final pre-season test.

“I hope we can, at least, but when that will be, who knows?”

Mercedes outfit have won just one race since comeback to the Formula 1 with Rosberg at 2012 Chinese Grand Prix.

During the first and second pre-season test at Jerez and Barcelona respectively, Mercedes guys struggled with downforce comparatively front runners. But the final pre-season test data shows they achieved lots of improvements.

“I don’t think it’s anything you need to be impressed with really, I think everyone’s doing their own programmes and everyone’s on different fuel loads so it’s just another testing day for us.” he said of today’s time.

“I think it’s important to bring everyone back down to Earth and realise that we’ve still got a lot of work to do.

“But Mercedes are doing a great job, both in the engine department and also with the car, it’s obviously a lot better than it was last year.”
